Addressing fix for: Clickhouse crash issue on power pc build #267

Open harishisnow opened 2 months ago

harishisnow commented 2 months ago

ClickHouse power pc build release version crashes by using following SQL(which is essentially functional test 02287_legacy_column_name_of_tuple_literal_over_distributed):

select if(in(dummy, tuple(0, 1)), 'ok', 'ok') from remote('localhost', system.one) settings legacy_column_name_of_tuple_literal=1, prefer_localhost_replica=0;

Note that debug version(with -O0 option to compile) works fine which indicates it could be a compiler optimization issue.

A llvm github issue was created: https://github.com/llvm/llvm-project/issues/102311
